Hello! I have successfully installed xen and run a domU on a debian squeeze. I have followed step by step the tutorial from Falko here. I can log in my domU by SSH but from the domU I can't connect to anything but the dom0 itself. Can anyone help me to enable network from my domU to the ouside? Here is my xend-config.sxp file: Code: [email protected][email protected] Here is my domU.cfg file: Code: [email protected] I don't have any xenbr when I run ifconfig: only eth0, peth0, lo and vif1.0 When I run tshark -f '!port 22' I can see ARP requests when I try to ping others hosts than my dom0 but no answer. It looks like these ARP packets ar stuck in the dom0 host. Here is iptables -L output: Code: Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED PHYSDEV match --physdev-out vif1.0 ACCEPT udp -- anywhere anywhere PHYSDEV match --physdev-in vif1.0 udp spt:bootpc dpt:bootps ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED PHYSDEV match --physdev-out vif1.0 ACCEPT all -- namaka-vm.telergos.net anywhere PHYSDEV match --physdev-in vif1.0 I am ways too newbie to fully understand this configuration, but it looks like it is applied at boot time. I have thought that dom0 may not know what to do with domU packets, but do0 is supposed to act as a bridge! So, it should simply relay these packets on its eth0 interface, letting my switch relay them on the others hosts... Thank you for your time and help!
